Ops Marine

There are two types of divers in the Army and the Navy. I believe both classes go to Navy schools.

The Army Salvage diver is akin to the Navy diver which makes underwater repairs.

The Army special ops diver goes to the Navy school as does Marine Recon and MARSOC. The Marine Corps is the only one which has combat divers who aren't special ops. Army special ops, Marine ForCon, MARSOC, and SEALs all go to the same Navy schools.
